Liz Mittal is an Engineer III with the Center for 21st Century Toxicology. She specializes in computational analysis, environmental modeling, risk assessments, and process engineering. She is skilled at managing and analyzing extensive environmental data sets, and she has developed indoor air quality models to assess risks from household consumer products. Ms. Mittal’s expertise includes conducting dose-response modeling for various chemicals to derive points of departure. She holds a master’s degree from the University of Texas at Austin, in Environmental and Water Resources Engineering. Her graduate research focused on innovative approaches to characterizing and monitoring exposure to sediment contaminants during remediation. She has conducted field studies using a novel passive sampling technique to evaluate the effectiveness of remedy caps at Superfund sites. She has also conducted laboratory investigations to quantify the sorption of contaminants onto various amendments for capping remedies. Prior to her work in the field of environmental engineering, Ms. Mittal was a practicing chemical engineer in the semiconductor industry, designing and optimizing key manufacturing processes.
